Description

Technical Field

[0001] The present disclosure relates to the field of electrical engineering technology, and in particular to a distribution line ice melting system, a control method, a medium and an electronic device. Background Art

[0002] The power grid is prone to rain, snow and freezing disasters. Severe ice on the transmission and distribution lines can easily cause tower collapse and line breakage, which seriously threatens the safe operation of the power grid. The rural distribution network is the last mile of power supply for daily life, and power supply reliability is particularly important. However, many rural distribution network lines are distributed in micro-topography and micro-meteorological areas, and are severely covered with ice in winter. It is very easy to cause line outages due to pole collapse and line breakage, which seriously affects normal production and daily electricity consumption.

[0003] Electric current ice melting is an effective means to deal with ice on agricultural distribution lines. For example, direct current ice melting is used. The direct current ice melting device converts alternating current into direct current, connects to the distribution line, and short-circuits the three phases at the end of the line to form an ice melting circuit to achieve ice melting on the line. However, there are a large number of distribution transformers connected along the distribution line. The direct current ice melting voltage will form a loop in the primary winding of the distribution transformer, which may easily cause the transformer direct current to burn the coil. Therefore, before ice melting, the distribution transformers along the line are usually opened manually, and then closed after the ice melting is completed, resulting in a large amount of manual work and increased danger due to ice on the roads in winter.

[0033] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0035] The present disclosure provides a distribution line ice melting system. Figure 1 A schematic diagram of a power distribution line de-icing system according to an embodiment of the present disclosure is provided. Figure 1 The ice-melting system includes: a power distribution device 1, an ice-melting device 2, a first switch 3, a second switch 4, an ice-melting isolation unit 5 and a distribution transformer 6.

[0036] The input end of the distribution line 10 is electrically connected to the distribution device 1 through the first switch 3 , and is electrically connected to the ice-melting device 2 through the second switch 4 ; the distribution transformer 6 is connected to the distribution line 10 through the ice-melting isolation unit 5 .

[0037] The distribution device 1 is used to output AC power to the distribution line 10 when the first switch 3 is turned on and the second switch 4 is turned off, and convert the high voltage into low voltage through the distribution transformer 6 and transmit it to the load; the ice melting device 2 is used to output DC power to the distribution line 10 for ice melting operation when the first switch 3 is turned off and the second switch 4 is turned on; the ice melting isolation unit 5 is used to transmit AC power and block DC power.

[0038] Exemplarily, the ice melting system includes a power distribution device 1 and a first switch 3, wherein the input end of the power distribution device 1 is electrically connected to the AC power grid, and the output end of the power distribution device 1 is electrically connected to the distribution line 10. The power distribution device 1 can be a main transformer of a substation, converting high-voltage AC power in the AC power grid into lower AC power, and then transmitting it to the distribution line 10. In addition, the first switch 3 is electrically connected between the output end of the power distribution device 1 and the distribution line 10, and when the first switch 3 is turned on, the power distribution device 1 is connected to the distribution line 10.

[0039] The input end of the ice-melting isolation unit 5 is electrically connected to the distribution line 10, and the output end of the ice-melting isolation unit 5 is electrically connected to the input end of the distribution transformer 6, that is, in the distribution stage, the AC power transmitted from the distribution device 1 to the distribution line 10 enters the distribution transformer 6 through the ice-melting isolation unit 5, and the voltage is converted at the distribution transformer 6, and the high voltage is also converted to a low voltage and then transmitted to the load to supply power to the user. Since the ice-melting isolation unit 5 is used to transmit AC power and block DC power, in the distribution stage, the ice-melting isolation unit 5 can allow AC power to pass through without affecting the distribution operation.

[0040] The embodiment of the present disclosure also includes an ice melting device 2 and a second switch 4. The ice melting device 2 is electrically connected to the input end of the distribution line 10 through the second switch 4 to access the distribution line 10 and perform an ice melting operation on it. The ice melting device 2 is a DC ice melting device powered by a DC power supply. In the ice melting stage, the distribution device 1 stops supplying power to the distribution line 10, the second switch 4 is turned on, and the second end (line end) of the distribution line 10 is short-circuited ( Figure 1 In the short-circuited state, the ice-melting device 2 forms a loop with the ice-melting device 2. The ice-melting device 2 performs ice-melting operation by direct current to remove the ice and snow covering the distribution line 10. Since the direct current ice-melting method is adopted, the distribution line 10 is direct current, and the ice-melting isolation unit 5 is used to transmit alternating current and block direct current. Therefore, the direct current in the distribution line 10 is blocked by the ice-melting isolation unit 5 and will not be transmitted to the distribution transformer 6. It will not form a direct current loop with the primary winding in the distribution transformer 6, and there is no risk of direct current burning the coil of the distribution transformer 6. Furthermore, when performing the ice-melting operation, there is no need to pull the distribution transformer 6 and the distribution coil apart, and the connection state can be maintained, thereby reducing manual workload.

[0041] Specifically, since the power distribution device 1 and the ice-melting device 2 cannot work at the same time, different operations can be achieved by controlling the on and off of each switch. For example, in the power distribution stage, the first switch 3 is controlled to be on and the second switch 4 is controlled to be off, that is, the power distribution device 1 is connected to the distribution line 10, and the ice-melting device 2 does not need to be connected to the distribution line 10. At this time, the power distribution device 1 is started, and the power distribution device 1 outputs AC power to the distribution line 10, and the high voltage is converted into low voltage through the distribution transformer 6 and transmitted to the load, and the ice-melting isolation unit 5 will not hinder the AC power from entering the distribution transformer 6. In the ice-melting stage, the first switch 3 is controlled to be off and the second switch 4 is controlled to be on, that is, the ice-melting device 2 is connected to the distribution line 10, and the power distribution device 1 does not need to be connected to the distribution line 10. At this time, the ice-melting device 2 is started, and the ice-melting device 2 outputs DC power to the distribution line 10 for ice-melting operation, and the ice-melting isolation unit 5 blocks the DC power from entering the distribution transformer 6.

[0042] The distribution line de-icing system includes a plurality of distribution transformers 6, and the de-icing isolation units 5 are electrically connected to the distribution transformers 6 in a one-to-one correspondence, so a plurality of de-icing isolation units are also provided. The specific number of the distribution transformers 6 and the de-icing isolation units 5 can be set according to actual needs, and the present disclosure does not impose any specific restrictions on this.

[0043] In the disclosed embodiment, an ice-melting isolation unit is added to prevent DC current from entering the distribution transformer and burning the coil during the DC ice-melting process, and there is no need to manually separate the distribution transformer and the distribution lines one by one, thereby reducing the workload of the staff, ensuring personal safety, and improving the efficiency of DC ice-melting.

[0044] It should be noted that the embodiments of the present disclosure do not limit the specific structure and type of the first switch and the second switch, and they can be set according to actual needs. In addition, during the ice melting stage, the end of the distribution line needs to be short-circuited to form a loop. The short-circuiting can be done manually, or a switch can be set to control the end of the distribution line to short-circuit, which is selected according to actual needs.

[0045] In some embodiments, Figure 2 A schematic diagram of a power distribution line de-icing system according to an embodiment of the present disclosure is provided. Figure 2 Combined with Figure 1 , the power distribution line 10 includes a three-phase circuit; the ice-melting isolation unit 5 includes three groups of sub-isolation units.

[0046] Each sub-isolation unit is electrically connected to the three-phase circuit in a one-to-one correspondence.

[0047] Exemplarily, the distribution line 10 is a three-phase circuit, and correspondingly, the ice-melting isolation unit 5 includes three groups of sub-isolation units, each of which is electrically connected to the three-phase circuit in a one-to-one correspondence, so that during the ice-melting stage, the DC power in the distribution line 10 will not be transmitted to the distribution transformer 6 through any phase circuit in the three-phase circuit, avoiding the DC power and the primary winding in the distribution transformer 6 to form a DC loop, so there is no risk of the DC power burning the coil of the distribution transformer 6. Furthermore, when performing the ice-melting operation, it is not necessary to separate the distribution transformer 6 from the distribution coil, and the connection state can be maintained, reducing the manual workload.

[0048] In some embodiments, continue to refer to Figure 2 , the sub-isolation unit includes an inductor 51 and a capacitor 52.

[0049] A first end of the inductor 51 is electrically connected to the distribution line 10 , a second end of the inductor 51 is electrically connected to a first end of the capacitor 52 , and a second end of the capacitor 52 is electrically connected to an input end of the distribution transformer 6 .

[0050] Exemplarily, the sub-isolation unit includes an inductor 51 and a capacitor 52 connected in series to form a series resonant circuit. Since the capacitor 52 has a certain blocking effect on direct current, it can prevent direct current from entering the distribution transformer 6. Figure 2 As shown, in the power distribution stage, the AC power in the distribution line 10 passes through the inductor 51 and the capacitor 52 in sequence and enters the distribution transformer 6. In the ice melting stage, the DC power in the distribution line 10 will be blocked by the sub-isolation unit formed by the inductor 51 and the capacitor 52 and cannot pass through the inductor 51 and the capacitor 52 to enter the distribution transformer 6. In other embodiments, the positions of the inductor and the capacitor can be exchanged, and they can be connected in series.

[0051] It should be noted that the embodiments of the present disclosure do not limit the specific circuit structure within the sub-isolation unit, ensuring that it can achieve the function of transmitting alternating current and blocking direct current, and can be specifically configured according to actual needs.

[0052] In some embodiments, the equivalent impedance of the capacitor and the inductor is zero.

[0053] For example, although the series resonant circuit composed of capacitors and inductors can transmit AC power and block DC power, in the power distribution stage, the AC power in the distribution line is transmitted to the distribution transformer. However, the presence of capacitors and inductors will cause current loss to a certain extent, affecting the effective value of the transmission current. Therefore, the equivalent impedance of capacitors and inductors should be zero to reduce the consumption of AC power by capacitors and inductors so that they will not affect the normal operation of the distribution transformer.

[0054] In some embodiments, continue to refer to Figure 1 and Figure 2 , the sub-isolating unit further includes a third switch 53 .

[0055] A first end of the third switch 53 is electrically connected to a first end of the inductor 51 ; a second end of the third switch 53 is electrically connected to a second end of the capacitor 52 .

[0056] Exemplarily, a third switch 53 is connected in parallel at both ends of the series resonant circuit formed by the capacitor and the inductor, the first end of the third switch 53 is electrically connected to the first end of the inductor 51, and the second end of the third switch 53 is electrically connected to the second end of the capacitor 52. When the third switch 53 is turned on, the resistance of the branch is small, and the current is directly transmitted to the distribution transformer 6 through the third switch 53. When the third switch is turned off, the current cannot be transmitted to the distribution transformer 6 through the branch where the third switch 53 is located, but will be transmitted to the branch where the inductor 51 and the capacitor 52 are located. At this time, if the distribution line 10 is AC, it can be transmitted to the distribution transformer 6 through the inductor 51 and the capacitor 52. If the distribution line 10 is DC, it will be blocked by the inductor 51 and the capacitor 52 and cannot be transmitted to the distribution transformer 6, thereby preventing the distribution transformer 6 from being burned.

[0057] After the third switch 53 is set, in the power distribution stage, the third switch 53 can be turned on to allow the AC power to enter the distribution transformer 6 through the branch where the third switch 53 is located. In the ice melting stage, the third switch 53 is turned off so that the DC power is blocked by the sub-distribution unit. Although the AC power can also be transmitted to the distribution transformer 6 through the inductor 51 and the capacitor 52 in the power distribution stage, frequently passing the current through the inductor 51 and the capacitor 52 will reduce the life of the inductor 51 and the capacitor 52. Therefore, the third switch 53 is set to reduce the number of times the AC power passes through the inductor 51 and the capacitor 52, thereby increasing the life of the ice melting system.

[0058] The embodiments of the present disclosure also provide a control method for a distribution line ice melting system, which is applied to a distribution line ice melting system as in any one of the above embodiments. Figure 3 A flow chart of a control method for a power distribution line de-icing system provided by an embodiment of the present disclosure, referring to Figure 3 , the control method includes S110-S120:

[0059] S110. Obtain status information of a power distribution line.

[0060] S120: Based on the status information satisfying the ice-melting condition, control the first switch to be turned off and the second switch to be turned on, so that the ice-melting device outputs direct current to the power distribution line to perform an ice-melting operation.

[0061] For example, when using the distribution line de-icing system to perform de-icing operations, the state information of the distribution line must first be obtained to determine the degree of ice and snow coverage on the distribution line. If the state information of the distribution line meets the de-icing conditions, that is, the ice and snow coverage is relatively large, the distribution line de-icing system needs to be controlled to perform de-icing operations.

[0062] For example, the first switch is controlled to be turned off and the second switch is controlled to be turned on. At this time, the ice melting device is connected to the distribution line, and the connection between the distribution device and the distribution line is disconnected. In addition, the distribution line at the end of the distribution line needs to be short-circuited to form an ice melting circuit. At this time, the ice melting device is started, and the ice melting device outputs direct current to the distribution line to perform ice melting operation. The ice melting isolation unit blocks direct current from entering the distribution transformer to prevent the distribution transformer and the distribution line from forming a loop and burning the coil of the distribution transformer.

[0063] In some embodiments, it also includes:

[0064] Based on the state information satisfying the power distribution condition, the first switch is controlled to be turned on and the second switch is controlled to be turned off, so that the power distribution device outputs AC power to the power distribution line.

[0065] If it is determined based on the status information of the distribution line that the distribution line is not covered with ice or snow, there is no need to perform ice melting operations. It is determined that the distribution conditions are met and the distribution operation can be performed normally. The first switch can be controlled to be turned on and the second switch can be controlled to be turned off. At this time, the distribution device is connected to the distribution line, and the connection between the ice melting device and the distribution line is disconnected. At this time, the distribution device is started, and the distribution device outputs AC power to the distribution line, and the high voltage is converted into low voltage through the distribution transformer and then transmitted to the load. The ice melting isolation unit will not hinder the AC power from entering the distribution transformer, and power can be distributed to users normally. It should be noted that when performing the distribution operation, the end of the distribution line does not need to be short-circuited.

[0066] In some embodiments, before the ice melting device outputs direct current to the power distribution line to perform ice melting operation, the method further includes: controlling the third switch to be disconnected.

[0067] Exemplarily, the sub-isolation unit in the ice-melting isolation unit includes a capacitor and an inductor connected in series, and a third switch is connected in parallel at both ends of the series resonant circuit formed by the capacitor and the inductor. When the third switch is turned on, the resistance of the branch is small, and the current is directly transmitted to the distribution transformer through the third switch. When the third switch is turned off, the current cannot be transmitted to the distribution transformer through the branch where the third switch is located, but is transmitted to the branch where the capacitor and the inductor are located. Therefore, in order to prevent the ice-melting device from outputting direct current to the distribution line for ice-melting operation, the direct current enters the distribution transformer and burns the coil of the distribution transformer. Before performing the ice-melting operation, the third switch is controlled to be disconnected to achieve the isolation function.

[0068] In some optional embodiments, the ice melting system includes: a power distribution device, an ice melting device, a first switch, a second switch, an ice melting isolation unit, and a distribution transformer. The ice melting isolation unit includes three sub-isolation units, each of which includes a capacitor and an inductor, and a third switch connected in parallel at both ends of the capacitor and the inductor. Based on this structure, the complete process for power distribution and ice melting is as follows.

[0069] Specifically, the status information of the distribution line is obtained. If it is determined based on the status information that the distribution line operates normally and meets the distribution conditions, the distribution operation can be performed normally. The first switch is controlled to be turned on, the second switch is turned off, and the third switch is controlled to be turned on, and the distribution device is started. At this time, the load is powered by the distribution device, the first switch, the distribution line, the third switch in the ice melting isolation unit, and the distribution transformer. If it is determined based on the status information that the ice-covered season is about to begin, the third switch in the ice melting isolation unit can be turned off in advance. At this time, the load is powered by the distribution device, the first switch, the distribution line, the series resonant circuit composed of the capacitor and the inductor in the ice melting isolation unit, and the distribution transformer. Turn off the third switch in advance to avoid turning off the third switch in time after ice is covered, resulting in direct current being transmitted to the distribution transformer and burning the coil of the distribution transformer. If the status information of the distribution line meets the ice melting conditions, that is, there is a lot of ice and snow coverage, the first switch is controlled to be turned off, the second switch is controlled to be turned on, the third switch continues to remain in the off state, and the three phases at the end of the distribution line are short-circuited. When the ice melting device is started, there is direct current in the distribution line, but the capacitor in the ice melting isolation unit blocks the direct current. Therefore, the direct current voltage cannot form a direct current circuit with the primary winding of the distribution transformer through the ice melting isolation unit, and will not burn the coil in the distribution transformer, nor will it manually disconnect the distribution transformer from the distribution line. After the ice melting is completed, the ice melting device is turned off, and the first switch is controlled to be turned on and the second switch is turned off. When the ice-covered season is over, the third switch can be turned on, and the distribution transformer is no longer electrically connected to the distribution line through the inductor and capacitor, and can supply power normally.

[0070] The embodiments of the present disclosure further provide a computer-readable storage medium having a computer program stored thereon.
